Buying a classic sound always comes at a price. This is not only true of buying a Moog Voyager. Today a Gibson Les Paul guitar can cost between $2,500 - $3,500 If you want an authentic classic sound you pay the price otherwise you have to look at alternative options. It really just depends on what your needs and financial situation are.

Personally, be it guitars or keyboards, I look for value in lower priced gear.
